It's called The Mercury 13: The Secret Astronauts. I don't think that's actually true...Jerrie Cobb at least got several bits of news coverage out of it... at least one article in Life...

Here's the URL to part 1:
The Mercury 13 underwent the same tests as the male astronauts of the Mercury 7, but they were never really a group. They were tested individually, and it wasn't an official program, although they fought hard for their right to go into space, before President Lyndon Johnson put the kibosh on it by changing the rules so that astronaut candidates had to have jet experience. To that time, only Jackie Cochran had ever flown a jet - and that only very briefly, thanks to her good friend Chuck Yeager.
